4 Claims.

The object of my invention is to provide a stove of the type usinggasoline under pressure or the like, which is provided with a pluralityof burners and which has a push button lighter, whereby all but themaster burner may be conveniently and easily lighted from the masterburner.

Another object is to provide such a structure in which a pilot light maybe eliminated.

It is my particular object to provide a novel and inexpensive andeiiicient structure in such a lighter device.

With these and other objects in view, my invention consists in theconstruction, arrangement and combination of the various parts of mypush button lighter, wherebythe objects contemplated are attained, ashereinafter more fully set forth, pointed out in my claims, andillustrated in the accompanying drawing, in which:-

Figure 1 is a top or plan view of a burner equipped with a push buttonlighter embodying my invention, parts being broken away and parts beingshown inv section.

Figure 2 is a detail, sectional view taken on the line 2-2 of Figure 1.

Figure 3 is a detail, sectional View taken on the line 3-3 of Figure 2;and

Figure 4 is a detail, sectional View taken on the line 4 4 of Figure 2.

I shall first describe in a general way the burner structure. The burnermanifold is indicated generally at A, and is of peculiar irregular form,varying according to the number of burners proper with which the stoveis equipped and varying with other features of stove construc' tion.

The manifold here illustrated is a hollow one with a transverselyextending portion I6. From the manifold portion I6 extend the passagesI1, I8, I9, and 20 to four burners with which the stove is provided.Three of the burners are indicated at Ila, l8a, and 20a.. The burner20a, is the master burner.y The burner connected with the passage I9 isomitted but is like the others. v

An intake passage 22 leads to the manifold portion I6 and anotherpassage 23 leads from the manifold portion I6 to the passage 24 to thegenerator burner 25 of the ordinary saw-kerf type.

Arranged above the generator burner 25 and communicating with the intakepassage 22 is a generator 3|. Fuel is supplied to the generator 3l andthence to the manifold through a valve 1935, Serial N0. 27,201

43, which is automatically controlled by means of a thermostat 44.

Valve control rods 63, 64, 65, and 66 and ordinary valves not shown indetail, control the flow of fuel from the fuel manifold to the variousburners. A valve 40 controls the flow of fuel from the generator to themanifold.

In Figure 1, I have shown at 10 what may be called the generator burnerlighter'. It is similar in construction to parts of the push buttonlighter to be later described, and will` be referred to again. It issuflicient for the present to say that this burner lighter 'I0 is ofsuch construction that when the valve 40and the valve controlled by rod63, are opened, and the master burner is lighted, fuel will pass to thegenerator burner 25 and thence upwardly through the lighter 10, where itwill be lighted by the flame from the master burner 20a and flame willthen pass down through the lighter 'Hl to the generator burner forigniting the fuel escaping from the generator burner.

I shall now describe in greater detail the push button lighterstructure.

Communicating with the manifold section i6 is a tubular elbow tting 14,best shown in Figure 2.

At the inner end of the fitting 14 is a valve seat 15 with which coactsa disc valve 16 on a stem 'Il slidably projecting through the wall ofthe iitting i4 and then extending toward the front of the stove, andprovided at its outer end with a push button head 78.

On the stem 11 'spaced from the fitting 'M is a fixed collar 19. A coilspring 8l] is arranged on the stem 1l between the collar 'I9 and thefitting 'i4 under compression, so that it normally holds the valve 16tightly seated.

By pressing the head 'I8 inwardly against the tension of the spring 80,the valve 'i6 can be opened for allowing fuel vapors to pass from themanifold into and through the fitting 14.

The burner lighter structure now to be described can be assembled as aunit, and set onl the upper end of the fitting 14.

This lighter structure includes a sleeve 8l, telescopically receivingthe upper end of the fitting lil and having a top 82 spaced above thefitting 14, and provided with a series of small perforations 83.

The tube 84 communicates with the interior of the sleeve 8| near the topthereof and extends slightly downwardly to position close to thegenerator burner 25.

Similar tubes 85 communicate with the upper interior of the sleeve 8land extend to the other burners.

The tubes 84 and 85 have in their tops longitudinal narrow slots 86.

The outer end of the tube 84 is closed as at 84a, while the tubes 85preferably have filter screens 81 at their outer ends. The tube 84 has adownwardly opening, channel-shaped hood 88 receiving the tube 84 betweenits lower side walls, as shown in Figure 2. The tube 88 is open at itslower end adjacent the generator burner 25. The tubes 85 havesubstantially similar channel-shaped hoods 89 partially receiving themand partially above them. The hoods 89 are substantially closed at theirouter ends as at 90. y

Each hood 85 has at its outer end at itstop, an opening 9|.

On the top of the sleeve 8| is a cap 92 having an annular, downwardlyextending flange 92a provided with an internal shoulder .93 -restin'go'nthe top 83. The flange 92a extends downwardly and forms an apron aroundthe upper part of the sleeve 8|. In Ythe flange 92a is a series ofnotches 94 to receive the ends of the hoods 88-89. The cap 92 is held inplace on the sleeve 8| by means of a screw r95 extended through the capand screwed into the top 82.

The generator lighter 10 shown in Figure 1 is similar in generalconstruction to the lighter members already described, having aninterior tube similar to the tubes 84-85, its lower end being closed asin the case of the outer end of the tube 84, and its upper end having ascreen as in the tubes 85. The lighter 'I0 has an outer hood similar tothe hood 89.

Operation of push, button lighter Until the valve 16 is opened, the pushbutton lighter ordinarily performs no particular function. Assuming,however, that the generator burner 25 has been lighted from the masterburner in the way heretofore described, then the push button lighter maybe used lfor the purpose for which it is intended. In this connection.it may perhaps be mentioned that the tube 84 and hood 88 could beconnected with the Vmaster burner instead of the generator burner ifthat were desired. It might also be mentioned that one reason forlighting the master burner 20a instead of the generator burner instarting the stove is that the burner 20a is conveniently accessiblewhen a dirt tray is in place over the burner, whereas the generatorburner is not then readily accessible for lighting.

When it is desired to light any one of the other burners (Ila, |8a or|9a) from the burner 25, the operator simply pushes on the head 18 andopens the valve 16 (see Figures 1 and 2) Thereupon gas or fumes from themanifold section .I6 pass through the fitting 14 into the sleeve 8l andthence through the various tubes 84-85 to the various burners. Gasescaping from the lower end of the tube 84 is ignited from the flame ofthe burner 25 and then the flame follows along under the hood 88 whichguides the flame along the slot 86 and prevents its blowing away. Theflame then passes into the cap 92, and then passes to all of the otherburners (Ila, |8a and |9a) and if either of the valves controlled by therods 64, 65 or 68 is open, the fuel escaping from the correspondingburner will be ignited.

I have thus provided a rather simple and very efficient structurewhereby after the master burner is lighted and the generator burner isburning, any of the three other burners mentioned may be lighted almostinstantaneously and very easily by pushing in on the button or head 18.

It may be mentioned that the sleeve 8| can be simply lifted off thefitting 14 and the assembly including the sleeve 8|, cap 92, tubes 84-85and hoods 88-89 may thus be removed or installed as a unit.

It Will be obvious that I have provided a very simple and inexpensivepush button lighter, by which any of the other burners of the stove may-lbeconveniently and easily lighted after the master burner has beenstarted.

It will,` of course, be understood that the details `of the constructionand arrangement of the parts of my push button lighter and the materialsof which they are made may be varied according to circumstances.

It is my intention to cover by my claims any changes or modifications inthe structure, arrangement and combination of the parts which may bereasonably included within the scope of such claims and within the scopeof my invention.
